Place it at the end of a rejection scene, after the setup has already made the snub clear, so the reaction carries the punchline. Follow it with Emotional Damage for a second reaction, or lead into it with Sad Meow Song to set up the scene before the main reaction arrives.

This is a long Portuguese voice clip built around the words abandonada por você, spoken as if a small rejection were a grand farewell that keeps going. It feels theatrically heartbroken and funny at once, because the sorrow is far bigger than the situation deserves. The line comes from Brazilian Portuguese, where vc is informal shorthand for você, meaning abandoned by you.
